The algorithm for body-fitted coordinate grids generation is one of the key techniques of numerical simulation in hydrokinetics. The previous researches on this technique were rarely combined with the Geographic Information System (GIS), so resulting in a low-level atomization of grids generation. On the other hand, the stability and precision of numerical computation are the chief concerned matters in single kinetic issues, which undoubtedly reduce the computation speed. To meet the quick-reaction need of the Emergency System, an automatic generation algorithm of body-fitted coordinate grids based on GIS is then put forward. Finally, the algorithm is realized through an example.
